IMPROVED MACHINE FOR CABIBURETTING AIR TO PRODUCE INFLAMMABLE GAS.

W113 gtlgaulenferra in it time germ tlltl t and mating and mi flge nmte.

Be it known that I, LEVI STEVENS, of Fitchburg, in the county ofWorcester, and Commonwealth of Massaehusetts, have invented a new anduseful Apparatus for Oarburetting Air for Producing Inflammable Gas; andI do hereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing bad to the annexed drawings, making a part of this specification,in which- Figure 1 is a view of one ehd of the machine; and

Figure 5 is a view of the opposite end.

Figure 3 is a side view.

Figure 4 is a vertical longitudinal section of the apparatus or machine.

Figure 2 represents the inside of the tank A; and

Figure 6 represents the inside of the tank B.

C is a horizontal cylinder, which contains a meter-wheel that revolvesin gasoline or other liquid suitable for carburetting air, and alsosheets or disks of wire cloth or other material suitable fortlie-distribution of the gasoline, so as to present a large surface tothe air that it may be carburetted properly for use. it are disks ofwire cloth, attached to the axis of the meter-wheel. These may beincreased in number, and sheets of wire cloth may be so placed in thebuckets of the meter-wheel as to-obtain a large quantity of evaporatingsurface. Other material may be used as a substitute for wire cloth forthe purposes of aiding evaporation. e is a drum, by means of which poweris applied for moving the meter-wheel. 7t 7t are gearing-s, connectingthe drum c with the shaft of the meter-wheel m. llrcpresent themeter-whccl. 0 is a pipe for introducing the air into the machine. Theair thus introduced passes first into the chamber h, which is connectedwith the tank 13. The air then passes through the passages q g, whichmay be filled with fibrous material or other substance designed to aidin carburetting the air. The air then passes into the chanibcr r and tothe tube or pipe .9, and is thus introduced within the casettof themeter-wheel. By means of an apparatus hereafter to be described thegasoline is kept at a certain line in the meter-wheel case, which lineshould be near the centre thereof. The revolutions of the wheel,arranged as described, bring the air in contact with a great extent ofvaporizing surface. The air, thus carburctted, passes into the chamberat, thence through the tube a into the tank A. w is a tortuous passagein the tank A, which may be filled with fibrous material for the purposeof further aiding in the process of carburetting the air. The air, thuscarburettcd, is ready for use. The delivery pipe is not shown upon thedrawings, but it should be connected with the tank A. The gasoline isintroduced into the tank A through the tube a; it then passes into thechamber :6, and thence through the tube y into the chamber The chamber.2 is connected with chamber 1) by a small opening, which is controlledby a flowage regulator, by means of which the gasoline is kept at therequired heightin the case of the. metenwheel. F is a float. E is thecase containing the float. f is an air pipe which connects the case ofthe mcter-whccl with the case E. d is a pipe which connects the lowerpart of the case E with the lower part of the case of the meter-wheel,so that the gasoline is always at the same level in both chambers. Thefloat F rests upon the gasoline. g is a lever, connected withthe bottomof the flout F. This lever is attached to the rod 7L, which is furnishedwith a valve adapted to the openingin the partition between the chamber.2 and the chamber 6. This valve is kept in place, so as to exclude theflow of gasoline into the chamber 5, by means of a spiral spring, j.When, however, the gasoline falls below the desired level in themeter-wheel case andvin the float case E, the float F falls, the lever 9draws back the red It, and the valve is opened for the flow oigasoline.When the gasoline rises in the caseE the weight of the float iswithdrawn from the lever, and the valve, by the aid of the spiralspring, is closed. I do not claim the meter-wheel, nor its use, for thepurpose of forcing air into evaporator-s or generators of gas machines,nor for the purpose of drawing air into or through such machines, but Iclainr the use of the meter-wheel for the purpose of carburettingatmospheric air in the manner substantially as described.

I also claim the fiowage regulator, constructed of the several partsspecified and arranged substantially as described and for the purposesset forth.
